HOW LARGE A ROLE SHOULD INDUSTRIAL ENERGY SAVINGS PLAY IN AN ENERGY POLICY BALANCING SAVINGS COSTS WITH RENEWABLE SUPPLY OPTIONS?

摘要

Energy savings are a key element in reaching ambitious fossil fuel reduction targets and may contribute to increased productivity as well. Fossil fuel reduction may be achieved also by other means as substituting with renewable energy. To compare and balance the effort in these two areas is an important task for policy design. For identification of the most attractive saving options in industry a thorough understanding of end-use demand and industrial processes is necessary to incorporate in the modelling. The paper develops three simulations describing the system wide consequences in Denmark of combined industrial energy savings and renewable supply options.Industrial energy savings/efficiency options in Denmark exist at various sub-sector and end-use levels even though the average energy intensity of Danish industry is low. This paper investigates savings options modelled in a very detailed setup of hourly demand levels for a range of end-use technologies in Danish industrial sectors.
